Study finds changes in the Arctic sea ice cover may be driving changes in atmospheric chemistry

Green Car Congress

The connection between changes in the Arctic Ocean’s ice cover and bromine chemical processes is determined by the interaction between the salt in sea ice, frigid temperatures and sunlight. Bromine also can remove ozone from the lowest layer of the atmosphere, the troposphere.

California ARB and NOAA Collaborating in $20M Research on Interaction of Air Pollution and Climate Change; One Atmosphere Approach

Green Car Congress

Although separate programs are in place to research and manage both air quality and climate change effects, these problems are not separate and in fact are intimately connected. The complex roles that ozone and aerosols play in the atmosphere provide examples of such trade-offs. 2010 CalNex Science and Implementation Plan.

New Comprehensive Lifecycle Energy and Emissions Inventory Includes Non-Operational Components; Large Aircraft Can Perform Better than Light Rail

Green Car Congress

Mikhail Chester and Arpad Horvath inventoried on-road, rail, and air travel to determine energy consumption, greenhouse gas (GHG) emissions, and criteria air pollutant (CAP) emissions (excluding PM, lead, and ozone due to lack of data). 83% of rail passenger kilometers are performed by metropolitan systems (with Amtrak serving the remaining).

SCOPE Biofuels Project Releases Assessment on Environmental Effects of Biofuel Technologies

Green Car Congress

A few studies also include other relevant impact indicators as acidification potential, eutrophication potential, ozone depletion potential and various toxicity potentials. However very few studies include water use impacts. In their paper on the impact of ethanol production on nutrient cycles and water quality, Simpson et al.

Here’s How We Could Brighten Clouds to Cool the Earth

Cars That Think

Take, for example, the tens of thousands of fossil-fueled ships that chug across the ocean, spewing plumes of pollutants that contribute to acid rain, ozone depletion, respiratory ailments, and global warming. Such clouds might be less likely to produce rain, and the retained cloud water would keep albedo high. Kate Murphy.
